You can go forward in time but you will never be able to go backwards in time. Time and space as one whole is called spacetime, The spacetime of the special theory is not Euclidean; meaning related to geometry. The typical interval is less than either the spatial or the time difference which makes the spacetime non-Euclidean.
All the laws are the same when dealing with physics. Newton's theory of gravity was related to his thoughts on space and time, and he formalized his concept of the inertial frame. Later a guy named Maxwell had a theory that electricity and magnetism contained a single number for the speed of light. Einstein then went over the situations and came to the conclusion that maxwell was right and newton's theory was an approximation.
This picture shows the equations of light recieved and light emited.
The first evidence is the equations of a quared interval which are: interval = square root of[(speed of light)2 * (time interval)2 - (space interval)2].
the second piece of evidence is: (ds)2 = (ds')2, which means that the two events are the same for all inertial observers, which should allways be the same.
the last piece of evidence is the fallowing chart:
Twin
Age when trip started
Age at turn around
Age when traveler returns
Earth-based
20 years
43 years
66 years
Spaceship-based
20 years
30 years
40 years
This shows that when on earth time seems longer, yet when in space the time seems shorter, thus the body ages at different time creating something like time traveling.
this picture shows the speed of light in a time graph.
My reason for supporting the first evidence is because knowing the equation for the interval helps prove that you arnt just pulling numbers out of nowhere. Knowing these equations are very manditory because you need to prove your work. Without proving your work no one knows if its all made up or you actually can prove it to others.
The second piece of evidence is a simple equation that shows that two events are the same for all inertial observers. This evidence is mandatory because it shows it should allways be the same and it cant be different. The equation helps show that is is fact not opinon or estimats. Equations and problems are very helpful when showing someone if it is real evidence or not.
My reason for supporting the third evidence is that it is the fact that I twin can stay on earth while the other one goes to space and yet the ages and appearance are dramatic. I belive that going into space is like time traveling to the future but there is no way that you can go back in time. The path of life is in a forward motion, meaning only a one way road, so going backwards is like taboo.
These experiments and equations help show the reality of everything. The problems show evidence and confirm that everything is real and not just made up. Time travel is technically possible but you can only ever move forward. There is no way to move backwards, because time allways goes in one direction. There will never be a time where time goes backwards or in a different direction. Some people really believe that going into space is like time travel, but for others, they are just too caught up in fantasy time travel that they belive it is nothing like actual time travel.

Tells about the theory of relativity and Einstien's theory about space and time. Gives information about gravity and examples on how it is a good theory. This is a good, recourceful website because it has stable information and the basic knowledge that i have on me is the same on this website.

I choose this site because it had a lot of links and information on it. The site seemed very organized and things were very easy to find on it. It also had the same basic information as the other two sites that I bookmarked.
"General Relativity." NCSA Web archive bounce page. 7 Nov. 1995. 7 Feb. 2009 <http://srchive.ncsa.uiuc.edu/Cyberia/NumRel/GenRelativity.html>. I choose this site because it was simple and straight to the point. It wasn't full of rambling and it had the main points that were important to know. I found the information very easy to understand and even though it wasn't as long as the other sites it still provided great information.
